What term refers to a church that is financed through the government, where citizens are taxed to support one Protestant denomination?

The term that refers to a church that is financed through the government, where citizens are taxed to support one Protestant denomination, is "Established Church." An established church is one that is recognized by law and is supported financially by the government. In historical contexts, particularly in European countries, this system often meant that a particular denomination (such as the Anglican Church in England) received state support and was often the official religion of the nation. This arrangement could lead to certain privileges for the established church and its members, while nonconformists or followers of other denominations might not receive the same level of support or recognition.

The concept of an established church underscores the relationship between religion and government, highlighting how state support can influence the practice and governance of religion within a society. In contrast, a state church also reflects similar ideas but may not highlight the aspect of taxation as directly as "established church." The other options do not accurately capture the defined relationship between a specific denomination and government support.
